refactor(catalog): split v1.go into v1_defaults.go

Move default catalog construction, legacy ModelCatalog conversion, and
pricing/capability sanitization+validation helpers into v1_defaults.go.
Schema types, parsing, validation, compilation, loading, and lookups
remain in v1.go. Pure mechanical split, no behavior changes.
